Features Original imported Economical compressed air CS VA500 flow meter with RS485
Easy installation in existing piping through integrated measuring sec-
tion (1/4” to 2“)
High measuring accuracy due to defined measuring section (inlet and outlet section)
•Digital interfaces such as Modbus RTU, Ethernet (PoE) and M-Bus enable connection to higher-level systems such as energy ma- nagement systems, building management systems, SPS,...
•Easy and auordable installation
•Units freely selectable via keys at the display m³/h, m³/min, l/min, l/s, kg/h, kg/min, kg/s, cfm
•Compressed air counter up to 1.999.999.999 m³. Resetable to „zero“ via keypad
•Analogue output 4...20 mA, pulse output (galvanically separated)
•High measuring accuracy also in the lower measuring range (ideal for leakage measurement)
•Negligibly small loss of pressure
•Calorimetric measuring principle, no additional pressure and temperature measurement necessary, no mechanically moved parts
•Comprehensive diagnosis functions can be read out at the display or by remote access via Modbus-RTU like e. g. exceeding Max./ Min values °C, calibration cycle, error codes, serial number. All parameters can be read out and changed via Modbus
